Weber Grill Troubleshooting

One of the largest frustrations of any summer is a gas grill that won't light or won't heat up to the correct temperature.  Believe it or not, you can sort out the problem yourself and be up and grilling again in no time.  Below we have some easy DIY gas grill repairs for the Weber BBQ Grill.

Before we begin our Weber Grill Troubleshooting, a word on safety.  Always make sure you turn off your propane and disconnect it from the grill before you start working on it.  Also, be sure your grill has had time to cool off, or you could end up in the hospital with some nasty burns.

Now, let's begin our Weber Grill Troubleshooting.

Weber BBQ Grill Propane Levels

  • Confirm you have propane in your tank. 
  • Check the tank and regulator hose for any signs of a leak. 
  • Replace any damaged parts before trying to ignite your Weber BBQ Grill again.

Testing Burners on Weber BBQ Grill

If you do not have an issue with your tank or hose, you need to check a few other things. By process of elimination, you can figure out the source of your lack of flame, or weakened flames, and how to fix it.

Web BBQ Grill will not Light

  • Check for gas flow by trying to ignite the burners manually using a long-handled match or lighter with the valve open.
  • If you do not get ignition this way, we know that our problem is with the pressure regulator.
  • If all ignited well, then gas flow is not the problem, and it is most likely an issue with the spark igniter.
  • If one or more will ignite but not all of them, it is probable you have a damaged or clogged burner, manifold, or spark igniter.

Weber BBQ Grill Pressure Regulator Repair

Sometimes your grill will go into bypass mode if it, correctly or incorrectly, detects a gas leak.  It is possible to accidentally cause your Weber BBQ Grill’s Pressure Regulator to go accidentally into bypass mode.  Resetting the regulator is a simple matter but could differ depending on the model of Weber BBQ Grill you purchased so be sure to check your user’s guide to confirm there are not additional steps you should be taking.

  • Turn off burners.
  • Close tank valve.
  • Wait 60 seconds.
  • Open tank valve fully and wait ten seconds for pressure in regulator to equalize.
  • Open grill lid.
  • Open one of the burner control knobs.
  • Light the grill.
  • Turn all burners to high and close lid.
  • Flames should heat grill to 500°F in a matter of minutes.
  • If this does not work for you, repeat the process and be sure to wait for the full 60 seconds in step three.

Weber BBQ Grill Igniter Electrode Repair

When you click that button to spark your igniter and get the grill going, it is the igniter electrode that produces the real spark. 

  • Look at the alignment of your igniter and make any needed adjustments.
  • Inspect the Electrode for any debris, build-up of food or carbon and clean it as necessary.
  • Some igniter systems have a battery, so it is possible your battery has gone out or is very weak.  Replace this as necessary.
  • If you still can't get a spark, or if your electrode seems damaged, you can replace yours by consulting your owner's manual.

Weber BBQ Grill Clogged/Damaged Burner Repair

When the flame is ignited, propane gas spreads across the burner.  Clogs in or damage to your burner can prevent it from lighting.

  • Remove burner grates
  • Remove flavor bars
  • Inspect inside of burner tubes
  • Inspect burner ports.
  • Remove debris and clean food spills.
  • Cleanse your ports and burners with a bottlebrush or stiff wire.
  • If you find damage or rust, you will need to replace the burner as per the instructions in our owner's manual.

Weber BBQ Grill Ignition Module Repair

Your ignition module transfers current to the igniter electrode and that arcs to light the gas. 

  • Replace the ignition module battery if necessary.
  • If you still do not have a current going to the igniter electrode, you will need to replace your ignition model as per your owner's guide.

Yellow Flames on my Weber BBQ Grill

Yellow flames are a clear sign you have something wrong with your Web BBQ Grill.  Your flames should always be blue (with yellow tips) while using propane gas in your girl. 

Stuck Regulator on Weber BBQ Grill

  • Turn off the gas.
  • Disconnect gas line.
  • Open Grill.
  • Turn all controls to high.
  • Wait for Sixty Seconds.
  • Turn controls off.
  • Reconnect gas line.
  • Slowly turn on the gas.
  • Light grill normally.
  • Inspect burner for proper ignition and color of flames.

Burner Adjustment on Weber BBQ Grill

  • Go under/inside your grill.
  • Look for adjustment point where burner connects to the manifold (normally behind control valves - consult your owner's guide to find an adjustment screw.)
  • Loosen the screw and rotate the metal sleeve.
  • Remove the cooking barriers and grates over burners so you can see flames.
  • Cool grill.
  • Loosen adjustment screw.
  • Rotate adjustment sleeve.
  • Tighten the screw.
  • Relight grill.
  • Repeat as necessary until flames are mostly blue with yellow tips.

Cleaning & Aligning Weber BBQ Grill

Debris, burnt grease, or carbon buildup on your burner can block the ports which the flame comes through.  This can lead to yellow flame.  Follow the instructions in your owner's manual on how to safely clean your Weber BBQ Grill.

Yellow flames persisting?  You could have an alignment problem.  Your manifold, control valve, and burners might not be aligned in the best possible way. Your gas needs to flow as straight as possible through all the parts of your Weber BBQ Grill. Inspect the entire flow and be sure all parts are properly aligned and undamaged.

If you find that you still have the yellow flame on all the burners, then you need to replace your regulator.  If the problem is with only one burner, then you most likely still have a clog or that part may be faulty.
